I feel spiritual experiences are usually inner experiences, so I gave up trying to figure them out or prove them. They're usually beautiful experiences, and that's enough for me. But I can relate to what you're saying. Up till my late 40's I've always been very spiritual, but then completely lost it. Felt dead. It took a few years to start coming back. It's only been a few months now, but it feels sooo good to feel that spiritual connection again.
I hope and pray you get your spiritual connection back, soon! {hugs}
